BASF expands Ultramid Advance portfolio with non-halogenated flame retardant

BASF is now complementing its polyphthalamide (PPA) portfolio by Ultramid Advanced N3U42G6, a polyamide 9T with non-halogenated flame-retardant, which minimizes electro-corrosion of metal contacts in electric and electronics (E&E) parts for e-mobility.

New Ultramid Advanced N is ideal for high-voltage connectors in electric cars.

The flame-retardant PPA increases the safety and durability of high-voltage (HV) connectors in inverters, DC-DC converters and batteries of electric cars.

As one of the first E&E expert companies, the automotive supplier KOSTAL Kontakt Systeme, Lüdenscheid, Germany, now uses the new Ultramid Advanced N in several components in its high-voltage connector KS22 Class 4 for high-current modules.

The new grade with good flowability at thin wall thickness enables miniaturization and saves installation space for the HV-connector. It provides the connector with very high electrical insulation which beats aliphatic polyamides, especially at elevated temperatures. In addition, it has a high elongation at break so that there is no stress whitening when the different components are mounted.

The flame-retardant Ultramid Advanced N3U42G6 extends the lifetime of E&E components as it is halide-free according to EN 50642. It thus prevents contact corrosion and subsequent failure of sensitive electrical parts exposed to heat and moisture.

The PPA achieves fire protection class UL94 with V-0 at 0.25 mm. It also enables long-lasting color coding which is safety-relevant in areas with high voltages.

Pre-colored variants like the e-mobility standard orange RAL 2003 are available directly from BASF. For self-coloring, more than 50 inorganic and organic colorants, which are approved for coloring PPAs and show a heat stability up to 350°C, can be used.
